Which of these is a method or mathematical process for designing algorithms for problem solving?

A. binary

B. input

C. algorithm design

D. supervisor program

C. algorithm design

The correct answer is C. algorithm design. Algorithm design is the process of creating a step-by-step plan or procedure for solving a problem. This involves breaking down the problem into smaller, more manageable steps and determining the best way to solve each step in order to reach the desired solution.
